Continuity mistake: In one of the last scenes, Cate Blanchett's character is standing in the doorway of her son's room. She is wearing a blue striped dress. When she walks into the room, she's wearing a floral dress.

Other mistake: Early in the film, Valerie Barksdale (Hillary Swank) visits Annie Wilson (Cate Blanchett) for a psychic reading. Valerie has been severely beaten by her husband, and her badly black and blue eye is swollen shut. A day or two later she visits Annie again. Amazingly her eye appears to have completely healed, even though the other marks on her face are still visible.

Continuity mistake: During Donnie's murder trial, the defense lawyer talks about the death of Annie's husband. He says her husband was killed in an explosion at work in April. However, at the end of the movie, Annie and the kids visit the husband's grave and it lists his date of death as November.

Question: When Annie and her boys are coming home from the neighbour's place, next door, there's a blue light coming from the main bedroom. Leaving her boys, Annie goes into the house and there is all this noise that sounds like a radio not completely tuned in, of an evangelist preaching really loudly. Now, where is all this noise coming from: Annie's mind, Donnie's car radio parked outside? Or is it just for our benefit?
